It sounds like you have a dirty trailer wiring connector on either your trailer or truck that is preventing a couple of your trailer functions from working properly. Inspect and clean both of the connectors. It sounds like the brake output circuit and the running light circuit just aren't making a decent enough connection to function properly.

I attached a couple help articles on troubleshooting for you to check out as well.
